Trapped in a life-support capsule for eighteen years, Cheng Shuying unexpectedly awakens her "immortal heart," thus becoming the target hunted by the Changsheng Pavilion. Under the protection of her father Cheng Chuanhe, she and companions Lu Chunyu, Li Haoran, Qin Xi, A Mu and others assemble the Six Qi of Xuanyang, while opponent Chen Dezu also turns back in choice after choice. Facing Lin Canghai and the turbid qi crisis, the six go from fighting alone to life-and-death oneness, ultimately transforming the destiny of "one person keeping vigil" into a heritage jointly guarded by everyone for the mortal world.
